To all whom t may concern.

Be it known that l, dosi-:rn D. STAUFFER, a citizen of the United States, residing at Suplee, in the county of Chester and State of Pennsylvania, have vinvented certain new and vuseful Improvements in Railroad Concrete Ties; and l do herebydeelare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in railroad ties and has for its object the provision of a device'of the above character which is adapted to pro-v vide. a simple, safe and reliable support for the rails .of railroads.

Another object of my4 invention -is the provislon of a device which will eliminate the use of wood for such purposes and substitute therefor u material which is substantially indestructible.

l A.. further ob 'et of my invention is the provision of a device of the above character which will 'effectively prevent the rails oil railroads from spreading and causing wrecks thereby.` I

A still further object of my invention is the provision of a novel means for attachin the rails in position on the tie and provi ing a means whereby the attachment may be adjusted according to the wear thereon.

With the above and other objects in view ll will now proceed to describe-my invention in the following specification and accompanying drawings, in which,

Figure 1 is a detail erspective view 'of l my improved railroad tie showing the rails' as they` would appear in position thereon, Fig. 2 is a top plan view of my improved tie showing the rails in position, Fig. 3 is a crete or the like.

longitudinal sectional view of my improved tie taken on line 3-3 of Fig. 2, Fig. 4 is a transverse sectional view of my improved tie taken on linee-4 of Fig. 1, and Fig. 5 is a detail view of the rail attaching means.

Referring to the drawings by characters of reference 1 indicates the body portion Iot' my improved tie which is formed of plastic material, suol as con- A suitable centrally lo- '-cated longitudinally extending reinforcing plate 2 is embedded in the concrete and has welded thereon the laterallfy7 extending reinforcing plates 3. These plates are preferreferably .p

.thereof to lie over the flanges of the rails.

ably of thinner material than the centrally located plate 2 and are adapted to extend throughout substantially the entire length of their respective sections of the tie. Suitable reinforcing plates l are also embedded in the concrete at points near the up er and lower surfaces as clearly shown in FPig. 1. rlhe uppermost plate 4 is adapted to act as a rest for the base of the rail when the same is inplace. Suitable bolts 5 are extended through apertures in eachv of the plates, as clearly shown in the figures, and are provided with nuts by means-ofwhich the'whole isv clamped'rmly togetherjl. i

On the upper surface of the ti'j ns'willfbe apparentin Fig., 1, a portion yoitheconcrete is cut away to form the reist in whichthe rail is adapted to seat, the bottom of this rest being formed by the uppermost plate 4 which serves both purposes of a rest and a reinforcing plate. ll-mmediately adjacent the rest and at suitable points .with relation to the edges of the tie also provide theV adapted to extend. -From the drawings n? will be apparent that the wedge key illus- .trated in Fig. 5 may be eliminated and a suitable split key may be substituted there- 'for which owing toits bifurcated end ma) be securely fastened in pl are in the aperture in the bolt 7. A suitable rail engaging plate 11 is provided and is formed with a central aperture through which the bolt 7 extends. This plate is arranged to engage the flange of the rail with which it cooperates and firmly locks the same in the rail seat. After the rails have been seated in the proper position the. only operation remaining to be performed is that of placing the plates 11 in osition and allowing the elongated ends Upon placing the keys in position it will be apparent that the plates 11 will be prevented .from becomingr displaced and should any wear take place thereinupon further driving the keys into the apertures 9, it will be anvwear may be thus taken up.

plates may be brought anges of the rails and apparent that the firmly against the hile in the foregoing l have shown and described the preferred embodiment of my invention l Wish it to be understood that li may change the specific arrangement and combination' o parts without 'in any Way departing; from the spirit and scope of my invention as defined in the appended claims.

What is claimed is:n o 1.,' in a composition railroad tie, 'a body portion oi'A plastic material, a centrally lou cated reinforcing plate extendin throughout the'entire length of said boy portion, auxiliary reinforcing plates secured to the central reinforcing plate, the topmost nur;v ill-ary plate being adapted to form a seat for .the rail when the same is in place, and means connected to in position. l

2. In a composition railroad tie, a body portion comprising two sections formed of plastic material, a centrally disposed longitudinally vextending; reinforcing plate embeddedin said plastic material, the middle portion of said plate being thicker than the end portions thereof, auxiliary reinforcing the tie to hold the rail Maaate v plates connected to the centrally located reinorcing plate and embedded in the material, the uppermost auxiliary reinforcing plate' being adapted to form a seat for a railroad rail when the same is in place, and means immediately adjacent the rail seat to rigidly secure the rail therein when the device is in use.

3. ln a device of the character described a body portion comprising two sections ormed of plastic material, a longitudinally extending centrally plate embedded in saidv plastic material, auxiliary reinforcing plates connected to the centrall .disposed reinforcing plate, bolts emloed ed in said sections, each o'said bolts having transversely extendin tures therein, and plates adapted to s ip over said bolts and be secured thereon and thereby hold the rail in position when thedevice is in use.

in testimony whereof I atlix my signature in presence of two Witnesses.
